FREDERICK C. JAENEKE, OF MILWAUKEE, WISCONSIN.

WATER-HEATER.

Specification of Letters Patent.

Patented Mar. 1i), 1912.

Application filed September 2B, 1911. Serial No. 651,744.

To all whom 'it may concern.

Be it known that I, FREDERICK C. Jan- Nnkn, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of l/Viseonsin, have invented certain new and useful Improvements in I/Vater-Heaters; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specification, its object being to provide simple, economical and etlicient water-heaters for hot water heating systems, as well as to economize fuel and the labor of feeding the same to the tire-pots of said heaters.

Figure 1 of the drawings represents a vertical section view of a water-heater constructed in accordance with my invention, the plane of the section being indicated by line 1-1 in Figs. et, 5 and 6; Fig. 2, a similar view on the plane indicated by line 2-2 in Fig. 5; Fig. 8, a plan view of the heater with the smoke-flue of the same in horizontal section, and Figs. 4, 5 and G, horizontal section views of said heater on planes respectively indicated by lines 1 -4, 5-5 and 6-6 in Fig. 2.

Referring by numerals to the drawings, 7, 8, 9, 10 and 11 indicate a series of sections embodied in a cylindrical base-burner 7titer-heater of my invention, these sections being cast with reference to stacking of the same one upon another in fluid-tight spigotjoint union. The sections 7, 8, 9 and 10 are provided with outer registering ears 12 for the engagement of bolt-rods 13 upon which to run clamp-nuts, whereby said sections of the heater are firmly held together. The upper heater section is cast with an upwardly extending central cylindrical eXtension 7 in which a cylindrical fuel-magazine 14 is suspended. As a matter of detail the fuel-magazine is provided with an upper outer flange 14 that rests upon an inner upper iiange 7 of the extension 7 of the heater section 7, and bolted to ears 7 of said extension is a centrally apertured top plate 15 having a door 16 in hinge connection therewith to close said aperture and the fuel-magazine.

Rigidly secured within the heater-section 7 by any suitable means, is a circular partition 17 that surrounds the fuel-magazine and rests upon the top of the heater-section S'to which it may be also rigidly secured by any suitable means, and thus a waterehamber is provided in said heater-section 7. lommunicating with the waterchamber aforesaid are vertical water-channels 18 between inner and outer walls of the heatersection S, and these channels also communicate, through ports 19, with a water-chainber in the heater section 9. The heater section 7 is provided with a nipple Q0 with which to couple a hot water eduction pipe 21, and the heater section 9 is provided with a nipple 22 with which to couple a cold water induction pipe Q3. The heater-section 8 contains a tire-pot Q4 in register' with the aforesaid fuel-magazine, the bottom of the fire-pot being a pivotally movable grate 25, as herein shown, or any other suitable form of grate over an ashpit Q6 in said heatersection, an opening to the ashpit being closed by a suitable door 27, as is common practice in heaters of various kinds. The lire-chamber has an outlet 2S to a smoke-box extension 8 of the heater-section 8, and a cutoff 29 is provided for said outlet. Ports ot' the fire chamber are open to vertical ducts 30 between the inner and outer walls of the heater-section 8, and these ducts communicate with branches of a Y-shaped smoketrunk 32 in the heater-section 9, the stem of this trunk being provided with a spout 83 leading into a base-chamber 311 of the heater formed by the sections 10 and 11 of the same.

The heater is provided with a fine 35 connecting its base-chamber 3-1 and smokebox 8, and a check-draft opening 3G in the flue is controlled by a crank-controlled sliding damper 37. .The heater-section S has a fuel inlet 38 for which a door 39 is provided, and the heater-section 10 has a cleanout opening normally closed by a door 40. The heater-section 8 is shown provided with nipples ll1 with which to connect a heating coil of domestic hot-water tank if desired, otherwise these nipples are closed by means of plugs 42.

From the foregoing it will be understood that the heater is similar to a base-burner stove having a magazine from which fuel is automatically fed to the tire-pot, and that provision is had for circulating water above the fire-chamber, alongside the same and the ashpit, vertically of the saine, and about the smoke-trunk between said ashpit and the base-cornpart1nent of said heater, whereby the water is exposed to a great ainount of heat radiating surface and thus economically raised to a circulating temperature.

I claiin:

1. A water-heater having a smoke-trunk therein below the ashpit thereof in coinlnunication with a base-compartment that is open to a draft-flue, there being ducts leading from t-he fire-chamber of the h-eater to the smoke-trunk, and water circulating space above said fire-chamber, around the salne and said ashpit, and about said smoketrunk.

2. A water-heater provided with an upper fuel-magazine and having a smoke-trunk therein below the ashpit thereof in coininunication with a base-compartment that is open to a draft-flue, there being ducts leading from the lire-chamber of the heater to the smoke-trunk, and water circulating Space above said fire-chamber, around the saine and said ashpit7 and about said sinoletrunk.

3. A water-heater having a fire-chamber, ashpit and draft-flue section provided with vertical channels and ducts between .walls thereof; a base-compartment of the h-eater Open to the draft-flue, a smoke-trunk under the ashpit open to said ducts and base-coinpartinent, said channels being open to space about the smoke-trunk; and an upper waterchamber section in communicationl with said channels.

4. A water-heater having a fire-chamber, ashpit and draft-flue section provided with vertical channels and ducts between walls thereof; a base-compartment of the heater open to the draft-flue, a smoke-trunk under the ashpit open to said ducts and base-coinpartinent, said channels being open to space about the smoke-trunk; an upper waterchaniber section in communication with said channels7 and a fuel-magazine suspended within an upward extension of said waterchainber section.

5. A water-heater having a fire-chamber, ashpit and draft-Hue section provided with vertical channels and ducts between walls thereof; a base-Compartment of the heater open to the draft-Hue, a Y-shaped smoketrunk under the ashpit having its branches open to said ducts and its stem open to the base-Compartment, said channels being open to space about the smoke-trunk; and an upper water-chamber section in communication with said chainber.

In testimony that I claiin the foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukee and State of Visconsin in the presence of two witnesses.
